Question

I was wondering if someone could look at these problems and let me know what errors you see.

The pseudocode in this case is an algorithm

1. A store sells cups and plates for parties. The owners want a program that allows them to enter the price of a cup, the price of a plate, the number of cups purchased, the number of plates purchased, and the sales tax rate. The program should calculate and display the total cost of the purchase.

Inputs	Process	Outputs
cupPrice		totalCost
platePrice
cupNum
plateNum
taxRate

Pseudo Code:

1. Enter cupPrice and platePrice
2. Enter cupNum and plateNum
3. Enter taxRate
4. Calculate total of plates and cups by multiplying cupPrice by cupNum/platePrice by plateNum, then add together.
5. Multiply taxRate by total and add to total to find totalCost.
6. Display totalCost

Desk Check

cupPrice	platePrice	cupNum	plateNum	taxRate	totalCost
2	5	7	10	0.2	76.80
5	7	10	15	0.3	201.5

2. A sales manager wants a program that allows him to enter the sales made in each of two states. The program should calculate and display the commission, which is a percentage of the total sales. This percentage is called the commission rate and is 12%.

Inputs	Process	Outputs
firstState		commissionTotal
secondState
commissionRate

Pseudo Code:

1. Set value of comissionRate to .12
2. Enter firstState and secondState
3. Calculate commissionTotal by adding secondState and firstState then multiply the total by comissionRate and add together.
4. Display commissionTotal

Desk Check

firstState	secondState	comissionRate	commissionTotal
15000	12000	.12	(15000+12000=27000) 27000*.12=3240 3240+27000= 30240
1000	900	.12	(1000+900=1900) 1900*.12=228 228+1900= 2128

Answer 1

Everything is right for the 1st question.

For the 2nd part, you have to calculate the total commission and not the sales plus total commission.

Total commission is calculated by commission rate multiplied by total sales.

I edited your solution:

Pseudo Code:

1. Set value of comissionRate to .12
2. Enter firstState and secondState
3. Calculate commissionTotal by adding secondState and firstState then multiply the total by comissionRate
4. Display commissionTotal

Desk Check

firstState	secondState	comissionRate	commissionTotal
15000	12000	.12	(15000+12000=27000) 27000*.12=3240
1000	900	.12	(1000+900=1900) 1900*.12=228
